The resources
stanza describes the requirements a task needs to execute.
Resource requirements include memory, network, CPU, and more.
job "docs" {
group "example" {
task "server" {
resources {
cpu = 100
memory = 256
network {
mbits = 100
port "http" {}
port "ssh" {
static = 22
}
}
device "nvidia/gpu" {
count = 2
}
}
}
}
}

Parameters
cpu
(int: 100)
- Specifies the CPU required to run this task in MHz.memory
(int: 300)
- Specifies the memory required in MBnetwork
(Network: <optional>)
- Specifies the network requirements, including static and dynamic port allocations.device
(Device: <optional>)
- Specifies the device requirements. This may be repeated to request multiple device types.

Examples
The following examples only show the resources
stanzas. Remember that the
resources
stanza is only valid in the placements listed above.
» Memory
This example specifies the task requires 2 GB of RAM to operate. 2 GB is the equivalent of 2000 MB:
resources {
memory = 2000
}
» Network
This example shows network constraints as specified in the network stanza which require 1 Gbit of bandwidth, dynamically allocates two ports, and statically allocates one port:
resources {
network {
mbits = 1000
port "http" {}
port "https" {}
port "lb" {
static = "8889"
}
}
}
» Devices
This example shows a device constraints as specified in the device stanza which require two nvidia GPUs to be made available:
resources {
device "nvidia/gpu" {
count = 2
}
}
